In 2004, the Yukon Oil and Gas Management Branch in Whitehorse, arranged with the National Energy Board (NEB) in 2004 to compile formation tops for the Yukon oil and gas wells. Previously, Yukon well tops had been picked by a number of geologists from the Geological Survey of Canada (GSC). Many of these well tops were published in various GSC publications and in several editions of the NEB Schedule of Wells. This report is an effort to update and revise the formation tops and to offer a consistent data set spanning the entire territory.
In total, 73 oil and gas were drilled during the period 1957 to 2005. The majority of these wells were drilled between 1957 and 1985, however, there was been drilling activity in the Territory in 2004 and 2005.
Formation tops for this dataset were picked using wireline logs exclusively. The data are presented in both imperial and metric values to accommodate both historical and recent well data, as well as user preference. The data set is complemented by the Yukon Stratigraphic Correlation Chart v. 3.04.
Formation tops are useful for the regional mapping of subsurface horizons. A variety of information can be obtained from this type of mapping, including structural trends and facies boundaries. Using regional correlation of formation tops, cross-sections can be constructed to aid in the understanding of basin morphology.
The List of Wells and Formation Tops, Yukon Territory, version 1.0, is an evolving dataset. We encourage comments and notification of any errors. This dataset will be updated regularly when new research warrants revision.
